Neutron spectroscopy gives unique insight into microscopic dynamics and excitations in matter. Crystal spectrometers such as IN16B at the Institut Laue-Langevin in Grenoble (France) operating in backscattering provide high energy resolution down to sub-micro-eV. While IN16B serves its international user community for about a decade by now, we continuously strive to improve and extend its...
POWTEX is a TOF neutron powder diffractometer [1] under construction at MLZ. Funded by the Federal Ministry of Education and Research (BMBF, 05K22PA2), it is built by RWTH Aachen University and Forschungszentrum Jülich. Dedicated texture sample environments are contributed from Geo Science Centre at Göttingen University.
Several new concepts have been developed and components built. The two...
Magnetic systems are fertile ground for the design of novel quantum and topologically non-trivial states characterized by exotic excitations. Recent examples include spin chain and square-lattice low-dimensional antiferromagnets, quantum spin liquid candidates, spin-ice compounds, and unusual spin textures. These systems are not only of fundamental interest but may also pave the way to new...
Grazing incidence small angle neutron scattering (GISANS) is a powerful techniqu to investigate surface-near lateral structures on the nanometer scale. It is particulary useful in soft-matter experiments to disentangle surface near structures from bulk effects. But even in hard-matter magnetism the technique can be used to improve the signal when scattering from magnetic particles on or near...
Advances in neutron instrumentation and techniques offer new opportunities for researchers. At the same time there is an increasing demand to make measured data accessible to the wider community through improved research (meta)data- management, and for implementation of FAIR data principles by which data should be made Findable, Accessible, Interoperable and Reusable. The...
